Inverted air-tight containers for liquid are utilized in a Wide variety of machines and devices, usually for supplying small quantities of liquid to an open receptacle from which :said liquid may be removedin sniall quantities from time totime. A lowering of the level inithe open receptacle admits airlto the container and allcwstrnoreliquid to flow out to restore the 1 leveland then stops the flow.

Fig. 1 is a vertical section through the valve m ch m: at th wh m 9 he s h e h r a sh w n th h-sp iahhs h hls e hh mr Figs; 2}, 3 and 4 are angular viewsof this valve ns loch hs'm chhh s a isshand 6 e v lh kih t t a t r hw t e va v m hani m at t tto of Fig. 11 is a horizontal section on the line XIXI of Fig. 8.

The illustrated container 14 is hereinafter referred to as a can, although it is understood that this term is merely descriptive and not exclusive, which is positioned upon an open receptacle 10 of a machine for coating pieces of work with cement. v

The inverted can 14 is provided with a threaded neck 20 on which there is adjustably mounted a ring 22 by means of whichthe container is supported in position upon the rim 24 of a portion of the cement receptacle 10. By adjusting the ring 22 it is possible to vary the position of the lower end of the can with respect to the receptacle and thereby to determine the level of the cement in the receptacle 10.

Since the can is full of a liquid such as cement as it is inverted to bring the neck 20 of the can into the receptacle, valve means have been provided temporarily to close the outlet of the can and thereby to prevent spilling the contents. Secured by screws to the lower end of the neck 20 is a plate 26 having an opening 28 (Figs. 2 and 5) which may be closed by means of a rotatable valve plate 30. This valve plate 30 is provided with a similarly shaped opening 32 which may be brought into register with the opening 28, as the turn plate 30 slides over the surface of the plate 26, turning on a pivot screw 33. In its movement around the pivot screw 33, the plate 30 is held in close contact with saidplate 26 by means of a' flat spring 34, so as thereby to keep the contacting surfaces clean and to prevent leakage. It will be noted that the edge of the turn plate-30 is provided with a notch 36 (Fig. 4) which'may be brought into engagement with a rib 38 on the inside of the receptacle as the can is inserted therein. After the notched plate 30 and the rib 38 have been brought into engagement, the valve may be opened by rotating the can to bring the open ings 28 and 32 into register, as shown in Fig. 6.

It is desirable to make sure'that the operator shall not be able to remove the can while the valve is in open position. Accordingly, the can is provided with latches 40 which are pivotally mounted on the ring 22 and which can be hooked under a ledge 42 on the receptacle 10, It will be noted that a notch 44 (Fig. 2) is' provided on the under side of the ring 22 which is brought into engagement with the upper end of the rib 38 (see-Fig; 3) as the can is inserted in the receptacle. This prevents rotation of the ring 22 with respect to the receptacle 10 as the can is turned to open the valve or to adjust its position on the receptacle. 7

Provision is made as above stated for preventing release of the latches when the valve is open. To this end plungers 48 are provided on the latches which are guided in ears 49 onthe ring. Springs 51 on the plungers 48 press against the cars 49 normally to hold the latches 40 in engagement with the ledge 42 of the receptacle.

The neck 20 of the container is provided with radial side and one inclined side.

vertical grooves 46, which are not diametrically opposite, and the plungers 48 are positioned upon the adjacent sides of said latches to enter the grooves 46 in one position of the container can. This position, by reference to the rib 38 of the receptacle 16, is such that the valve plates 26 and 30 are positioned to close the outlet of the can. When the can is turned to open the Valve the grooves 46 no longer register with the plungers 48 and it is impossible to release the latches 40 to remove the can.

In the modified construction illustrated in Figs. 7 to 10, inclusive, one of the latches 40 is replaced by a jointed latch the lower portion 52 of which is adapted to engage the ledge 42 of the receptacle lO. The upper end of this lower portion 52 has a groove 54 to receive the lower end of the upper portion 56 which is held therein by means of a pivot pin 58. The inner side of the lower end of the upper part 56 fits rather closely against the bottom of the groove 54 so that inward movement of the upper portion 56 to the position shown in Fig. 7 is effective to tip the lower portion 52 away from the ledge 42. This lower end ofthe upper portion is also beveled at 60 toward the outside to permit movemerit of the upper portion 56 independently of the lower portion 52 so as to withdraw from one of two notches or grooves -74 or 76 a plunger 62 somewhat longer than the plunger 48 provided on the other latch. This plunger 62 is secured to the upper portion 56 of the latch 50 by means of a screw 64 passing through a slot 66 in the head of the plunger. A coiled spring 68 is provided as before between the head of the plunger and the ear 49 on the ring 22 through which said plunger is guided. A flat spring 70 secured to a lug 72 on the lower portion 52 of the latch bears against the head of the plunger 62 so as normally to hold the head of said plunger inwardly with respect to the screw 64 in a position in which the inner end of the plunger 62 engages one of the grooves 74, '76 in the neck of the can, thus it will be seen that the plunger 62 is normally held in position to engage the bottom of one of the grooves 74, 76 unless positive force is exerted to force it back and out of the groove.

With the construction illustrated in Figs. 7 to 11, the grooves '74 and 76 are constructed as shown in Fig. 11 and have one substantially I The radial sides are upon adjacent sides of the grooves. By means of this arrangement turning movement of the can through a predetermined fraction of a revolution, here approximately a half turn, to

close-or open the valve is permitted without manual release of the plunger 62. When the operator desires to turn the can to close the valve, it will not be necessary to press against the upper half 56 of the jointed latch but, upon rotation of the can, the plunger 62 will be cammed out of the groove '76 by the inclined side of'said groove and Will ride over the threaded surface of the neck into the other groove 74. This arrangement permits the operator to close or open the valve but prevents him from changing the adjustment of the level of the liquid in the receptacle more thanthat minimum amount which results from a half turn of the can with respect to the ring 22. The design is such, that is to say, the lengths of the plunger 62 and of the slot 66 are such, that when the plunger 62 is not in one of the grooves it will be impossible to move the latch 50 to the position shown in V 1,922,297 Fig. 7 so as therebyto release the can from the receptacle, and in only one positioniof the can,

where the groove 74 registers with the plunger to determine the level of the liquid in the receptacle 10, and, supposing that the form shown in Figs; '7 to 11 is being used, to thisend the upperportion 56 of the, latch 50 will be pulled outwardly so as to withdraw the plunger 62 from the grooves '74 and 76 in the neck of the can. The can will then be inverted in position on the receptacle, bringing first the notch 36 and then the notch 44 into engagement" with the rib33. The latches and will be free to snap, into engagement with the ledge ,42 on the receptacle, and the plunger 62 into the groove '16. After this, the can '14 may be rotated to open the valve. As the valveis opened, the plunger 62 willfride out of the groove "76 and into thegroove 74, thereby preventing further rotation in this direction to vary the height adjustment inadvertently; It will be impossible'to scribed, without. having remove the canfrom the receptacle Without releasing the locking means by pressing inwardly the upper ends of the latches 40 and50, and

this cannot be done unless the can had been r0- v tated' in the reverse direction to such a position that the valveis. closed and the grooves 74 and 76 are in ali-nement with the plungers 48and 62; i The form of the invention shown in Figs. 1 to 6 will be used substantially as above I dea broken latch 50, with its: advantages. 7
